Details of that case came to light after parts of Cosby's deposition were released to the media.

More than two dozen women have accused Cosby of drugging and assaulting them, including a valley woman.

"I made it a mission in life to not let this define me as a woman, or to steal anything away from my opportunities or my drive," said Barbara Bowman.

Cosby accuser Bowman spoke to FOX 10 from her home in Scottsdale. She says she feels vindicated, after years of people trying to discredit her story.

"I spent a lot of time patiently pursuing the truth and it is victorious, and validating to know and hear and see that my attacker, my rapist has admitted to it. And we have a big road ahead of us," said Bowman.

Bowman claims that Cosby drugged and raped her in the 1980's when she was an aspiring actress and model. She was 17 when the alleged attack occured.

"I don't feel attacked any longer, I spent 28 years being attacked, and I spent 10 years being ignored, and then in the last 7 months is when the vicious attacks began," she said.

Bowman said the reason she came forward was to be a voice for awareness and education of sexual assault.

"My statute of limitation was years gone by, there was no monetary incentive whatsoever. It was to expose his predatory behaviors, his crimes, and to empower these women," said Bowman.

The full interview with Bowman has been posted on FOX 10 Phoenix's YouTube page.
